Abstract

289,220. Smith, S. C. March 10, 1927. Right to Patent relinquished. Dry processes of extracting precious metals; precipitating.-A liquor containing platinum and other precious metals such as palladium, rhodium, iridium, gold, and silver obtained from a platinum ore, concentrate. or residue by treatment thereof with hydrochloric acid in conjunction with chlorine or. with a substance other than nitric acid which evolves chlorine or an oxide of chlorine during the treatment, is treated with zinc dust to precipitate the precious metals. The residue from the treatment of the ore &c. may comprise a concentrate of rhodium and iridium and may be treated, as by fusion with lead, for recovery of these metals.
